I've been thinking about it but I can't seem to move ahead.
sqrt(2) is irrational. It's binary representation has no pattern.
It would look like 1.0110101000001001111... and multiplying by 2^n would left-shift it n times.
Taking floor of this irrational number loses a portion of the number...
Spec of root 2 is that set of elements floor(k * (root 2)) ; k >= 0 .
I have no idea of how I can prove the statement in the question.
Prove that spec of root 2 contains infinitely many powers of 2.
I need ideas on how to proceed.
but those frequencies are integral multiples of some fundamental frequency.
There are no bands.
Here every possible energy in a band is possible,but energies between 2 bands isn't possible.
This,I don't understand.
In the E-k diagrams for a semiconductor material,what exactly is k?
I have read that it is a propagation constant,a wave vector.
But does movement in the semiconductor material represent corresponding changes in k?
I mean to ask if changes in k represent the physical movement in the...
I am reading about solid state electronics(semiconductors).
I've read that when atoms of many many atoms are brought close each other,as in a solid,
the energy levels of energy states of different atoms get split up into different closely lying energy states collectively forming a band...
We have an experiment on Hall Effect,in which we place a semiconductor material in the middle of a 2 poles of a magnet exactly in the middle so that a distance of 1 cm exists between the poles.
1.Why is a semiconductor placed?Will it make any difference with a metal?
2.Why a 1 cm...
ghwellsjr,I didn't completely understand that.
Thank You for your explanation.
But we have a formula of electrostatic force between two charges don't we?
Are you saying that the constants in that change with the motion.(pi and epsilon?)
I mean,doesn't the guy in motion have the...
They say it is impossible to know whether you're moving at constant velocity or at rest unless you look outside.
How about this:(no gravity please)
I take two known charges and hold them at a distance one above the other.
They repel.That is l I know.
Someone else outside says,that the...
I am now to choose what I must study for engineering.
So,I wanted some help.Everyone says "you must take what you like and what you will enjoy doing and what will make your job enjoyable".
But,I don't know what I'll learn in engineering and what job I'll have to do.
(I have to pick among...
How many images of a symmetrically placed object will be formed if 2 plane mirrors are fitted on ADJACENT walls of a room and another one on the top(roof)?
(mirrors are big)
2. The attempt at a solution
According to me,9.
because,3 direct images of the object are...
